On the "Mississippi Miracle:"
We've heard a lot about MS reading gains. The puzzle: in the Spencer (2024) study, MS NAEP math and scores in 4th grade increased by similar amounts. Perhaps retention, not instruction, is doing some of the work here?

When districts sued Texas for AI scoring, how did independent measurement experts help inform the case? At 1:45, I'm talking about the important, often unseen role of Technical Advisory Committees in evaluating testing (and AI) evidence. @ncme38.bsky.social #AIMECon www.xcdsystem.com/ncme/program...

Liberty Munson's great keynote to open @ncme38.bsky.social's AIME-Con. I asked for examples of GenAI tests where we have evidence they're more 1) engaging, 2) precise, 3) predictive, and 4) impactful than traditional alternatives. She cited early evidence by Khan and Duolingo. With more at AIME-Con!

The Education Department recently requested ideas on how to “modernize” the data collection and education research funding agency, and it sought to hire for a few positions.
